Description

Technical Field

[0001] This application belongs to the field of bolts, and particularly relates to an adjustable bolt. Background Technology

[0002] Bolts are mechanical parts, cylindrical threaded fasteners that are used with nuts. They consist of a head and a threaded shank (a cylinder with external threads). They are used to fasten two parts with through holes, and this type of connection is called a bolted connection.

[0003] The existing publication number CN221237023U discloses a quick disassembly device for construction, including an adjusting bolt body and a fixing nut. The adjusting bolt body includes an adjusting bolt body head at the upper end and an adjusting bolt body threaded portion at the lower end. The adjusting bolt body threaded portion is connected to the fixing nut. The lower end of the adjusting bolt body is provided with an adjusting bolt that can be quickly disassembled, and the adjusting bolt is provided with a threaded portion on its exterior, which can be connected to the fixing nut.

[0004] Although the bolts mentioned above can change the overall length of the bolt, the position of each adjusting bolt is unstable when they are assembled together. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing an adjustable bolt that can change the overall length of the bolt according to the bolt's usage requirements, while also making the position of each adjusting bolt more stable when assembled together.

[0006] This application provides an adjustable bolt, including a nut, and further comprising:

[0007] The main bolt is mounted on the nut;

[0008] The upper bolt is installed on the main bolt;

[0009] An adjusting bolt, which is mounted on the upper bolt;

[0010] The lower bolt is mounted on the adjusting bolt;

[0011] Mounting assembly, which is mounted on the upper bolt;

[0012] The mounting assembly includes a mounting post and a first screw hole. The mounting post is located on the adjusting bolt and the lower bolt, and the mounting post is provided with external threads. The first screw hole is located on the upper bolt and the adjusting bolt.

[0013] When constructing using bolts of different lengths, the mounting post on the adjusting bolt can be threaded into the first threaded hole of the upper bolt, and then the mounting post on the lower bolt can be threaded into the first threaded hole of the adjusting bolt. Multiple adjusting bolts can be installed between the upper and lower bolts to adjust the overall length of the bolt. The mounting assembly can change the overall length of the bolt according to the bolt's usage requirements, making the bolt more adaptable to different scenarios.

[0014] Furthermore, the mounting components also include:

[0015] A locking groove is provided on the upper bolt and the adjusting bolt;

[0016] Compression springs, wherein two compression springs are provided in the locking groove, and the two compression springs are symmetrically arranged on the side wall of the locking groove;

[0017] A stop block, which is mounted on a compression spring;

[0018] A plug-in block, which is mounted on a mounting post.

[0019] When assembling the upper bolt, lower bolt, and adjusting bolt, the user rotates the mounting post into the first screw hole. At this time, the plug-in block also rotates and inserts into the locking groove along with the mounting post. The lower end of the abutment block is arc-shaped, and the middle part is provided with a groove for locking the abutment block. The lower end of the plug-in block is cylindrical, and the upper end is frustoconical. When the plug-in block is slowly inserted into the locking groove, the plug-in block will abut against the arc-shaped end face of the lower end of the abutment block. As the plug-in block slowly moves in, the bottom block is pushed open to both sides of the locking groove. At this time, the compression spring is compressed until the plug-in block is pushed into the groove in the middle of the abutment block to lock the bottom block, thus fixing the position of the plug-in block. At this time, the compression spring applies a restoring force to the abutment block to hold the plug-in block in place. The cooperation between the abutment block and the plug-in block can make the connection state of each component more stable when assembling the upper bolt, lower bolt, and adjusting bolt.

[0020] Furthermore, a telescopic rod is installed on the locking groove, and the output end of the telescopic rod is connected to the stop block.

[0021] A telescopic rod is installed on the locking groove, and the output end of the telescopic rod is connected to the abutment block. When the abutment block abuts against and applies pressure to the compression spring, the telescopic rod connected to the abutment block will support the compression spring. The telescopic rod can prevent the compression spring from being bent and losing its elasticity during the compression process. At the same time, the packaging abutment block can be stably clamped by the force of the compression spring's return, which improves the stability of the engagement between the plug block and the abutment block.

[0022] Furthermore, the main bolt includes:

[0023] An expansion groove is provided on the main bolt;

[0024] The telescopic block is inserted into the telescopic groove and is connected to the upper bolt;

[0025] The second screw hole is provided on the nut;

[0026] A threaded rod is movably mounted on the telescopic block, and the thread on the threaded rod mates with a second threaded hole.

[0027] When further adjustment of the overall length of the bolt is required, the threaded rod is driven to rotate. When the threaded rod rotates, it causes the telescopic block to slide in the telescopic groove. At this time, the overall length of the bolt is adjusted according to the position of the telescopic block in the telescopic groove, so that the bolt length dimension adjustment is more precise.

[0028] Furthermore, the main bolt also includes:

[0029] A limiting groove is provided on the telescopic block;

[0030] A limiting plug is installed on the expansion groove. The limiting plug has a cross-shaped cross section and is inserted into the limiting groove.

[0031] The limiting groove and the limiting block are connected by insertion. The limiting block has a cross-shaped cross section. The connection between the limiting block and the limiting groove makes the connection between the telescopic groove and the telescopic block more stable, and at the same time avoids the situation where the main bolt rotates but does not drive the telescopic block to rotate.

[0032] Furthermore, the nut is provided with anti-slip texture.

[0033] The nut has anti-slip textures, which make it less likely for the user to slip out of their hand and prevent stripping of the threads when tightening the nut, thus improving the stability of the bolt.

[0034] The beneficial effects of this application are:

[0035] 1. The mounting component can be adjusted to change the overall length of the bolt according to the bolt's usage requirements, making the bolt more adaptable to different scenarios;

[0036] 2. The cooperation between the abutment block and the plug-in block can make the connection state of each component more stable when assembling the upper bolt, lower bolt and adjusting bolt;

[0037] 3. The telescopic rod can prevent the compression spring from being bent and losing its elasticity during the compression process. At the same time, the packaging block can be stably clamped by the force of the compression spring's return, which improves the stability of the engagement between the plug block and the block.

[0044] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0045] Example 1:

[0046] like Figure 1 , Figure 2 , Figure 3 As shown, this application embodiment provides an adjustable bolt, including a nut 100, and further comprising:

[0047] Main bolt 200, which is mounted on nut 100;

[0048] Upper bolt 300, which is mounted on main bolt 200;

[0049] Adjusting bolt 400, which is mounted on upper bolt 300;

[0050] Lower bolt 500, which is mounted on adjusting bolt 400;

[0051] Mounting component 600, which is mounted on upper bolt 300;

[0052] The mounting assembly 600 includes a mounting post 610 and a first screw hole 620. The mounting post 610 is located on the adjusting bolt 400 and the lower bolt 500, and is provided with external threads. The first screw hole 620 is located on the upper bolt 300 and the adjusting bolt 400.

[0053] When constructing using bolts of different lengths, the mounting post 610 on the adjusting bolt 400 can be threaded into the first threaded hole 620 of the upper bolt 300, and then the mounting post 610 on the lower bolt 500 can be threaded into the first threaded hole 620 of the adjusting bolt 400. Multiple adjusting bolts 400 can be installed between the upper bolt 300 and the lower bolt 500 to adjust the overall length of the bolt 400. The mounting assembly 600 can change the overall length of the bolt according to the usage requirements of the bolt, making the bolt more adaptable to different scenarios.

[0054] Example 2:

[0055] like Figure 3 As shown, this application embodiment provides an adjustable bolt, which, in addition to the above-mentioned technical features, the mounting assembly 600 further includes:

[0056] Locking groove 630, the locking groove 630 is provided on the upper bolt 300 and the adjusting bolt 400;

[0057] Compression spring 640, two compression springs 640 are provided in the locking groove 630, and the two compression springs 640 are symmetrically arranged on the side wall of the locking groove 630;

[0058] A stop block 650 is mounted on a compression spring 640;

[0059] A plug-in block 660 is mounted on a mounting post 610.

[0060] When assembling the upper bolt 300, lower bolt 500, and adjusting bolt 400, the user rotates the mounting post 610 into the first screw hole 620. At this time, the insertion block 660 also rotates and inserts into the locking groove 630 along with the mounting post 610. The lower end of the abutment block 650 is arc-shaped, and a groove for locking the post abutment block 650 is provided in the middle. The lower end of the insertion block 660 is cylindrical, and the upper end is frustoconical. When the insertion block 660 is slowly inserted into the locking groove 630, the insertion block 660 will abut against the arc-shaped end face of the lower end of the abutment block 650. As the plug block 660 slowly moves inward, the bottom block is pushed open to both sides of the locking groove 630. At this time, the compression spring 640 is compressed until the plug block 660 is pushed into the groove in the middle of the abutment block 650 to lock the bottom block, thus fixing the position of the plug block 660. At this time, the compression spring 640 applies a restoring force to the abutment block 650 to hold the plug block 660 in place. The cooperation between the abutment block 650 and the plug block 660 can make the connection state of each component more stable when assembling the upper bolt 300, the lower bolt 500 and the adjusting bolt 400.

[0063] A telescopic rod 670 is installed on the locking groove 630. The output end of the telescopic rod 670 is connected to the abutment block 650. When the abutment block 650 abuts against and applies pressure to the compression spring 640, the telescopic rod 670 connected to the abutment block 650 will support the compression spring 640. The telescopic rod 670 can prevent the compression spring 640 from being bent and losing its elasticity during compression. At the same time, the packaging abutment block 650 can be stably clamped by the force of the compression spring 640's return, improving the stability of the engagement between the plug-in block 660 and the abutment block 650.

[0069] A threaded rod 240 is movably mounted on a telescopic block 220, and the thread on the threaded rod 240 engages with a second threaded hole 230.

[0070] When further adjustment of the overall length of the bolt 400 is needed, the threaded rod 240 is driven to rotate. When the threaded rod 240 rotates, it causes the telescopic block 220 to slide in the telescopic groove 210. At this time, the overall length of the bolt is adjusted according to the position of the telescopic block 220 in the telescopic groove 210, so that the bolt length dimension adjustment is more precise.
